Do you know why do oceans shelter fewer species than land? A conundrum posed by Robert May in 1994.

This approach shows how integrating molecular and conventional data supports better fisheries decisions. Also, our approach is flexible, scalable, and applicable to other species and ecosystems. We will be looking forward to comments from the fisheries and eDNA communities.

Rather than replacing acoustic surveys, eDNA acts as a complementary signal. Our Bayesian framework allows integrating both data streams, capturing uncertainties and enhancing robustness. This work was a collaboration between @ednacollab.bsky.social and @azti.bsky.social

Our model links traditional acoustic-trawl data with eDNA concentration, providing a more comprehensive picture of fish distribution and abundance. Applied to anchovy in the Bay of Biscay, the model reflects known patterns, yet eDNA points to broader distribution and potentially higher abundance.

🚨 New preprint out!

We've developed a Bayesian joint model that combines acoustic-trawl and #eDNA concentration data to improve fish biomass estimates. A step forward for integrative stock assessment and for translating eDNA data into practice.

By combining historical datasets with a broad eDNA survey, we improved understanding of these migratory fishes' distribution. This international effort highlights the need for well-designed sampling & species-specific assays for effective long-term monitoring.

Using qPCR & dPCR, we found that qPCR efficiently detected shads, while dPCR’s higher sensitivity was crucial for spotting the elusive sea lamprey, which sheds less eDNA due to its larval stage being burrowed in sediments for years.

Monitoring diadromous fishes is key for conservation, but their complex life cycles make in-situ data collection tough. This study used #eDNA to track sea lamprey (Petromyzon marinus) & European shads (Alosa alosa & A. fallax) across 44 river basins in Spain, France, Ireland & the UK.

I am happy to share a new preprint from the team on using #eDNA for monitoring diadromous species, led by @mukeshbhendarkar.bsky.social from @azti.bsky.social and with the collaboration of several institutions and administrations: www.biorxiv.org/content/10.1...

After 20+ years in science, I realized my most cited paper is (by far!) my first one. It had a big impact on me too, as I learned rigor in analyses and the art of writing. Proud of young me, navigating peak impostor syndrome while figuring out her path post-PhD.

Our study showcases the usefulness of genetics to study the distribution of gelatinous organisms, often destroyed in net sampling, and highlights the importance of cross-disciplinary reanalyses of often underutilized data from costly surveys:

Siphonophore community composition is vertically structured. Moreover, we found that siphonophores without pneumatophores (gas-filled structures related with floatability) are dominat shallow oceanic layers, whereas siphonophores with pneumatophores dominate the deep sea.

Naiara Rodriguez-Ezpeleta @naiarare.bsky.social · Dec 11

We identified 42 species, representing about a quarter of all known siphonophores, some of which have wider distributions than previously thought. We provide insights into the existence of genetic variations within certain species that dominate some ocean basins or depth ranges.
